Dank je, Marco.
Still I don't know how to apply this command, just entering it on the
gdb commandline gives me a "Target 'None' cannot support this
command.". If I open gdb with the executable filename as first
argument, it gives the same error, but then Target 'exec' is
mentioned.
I feel like there must be some way to apply this command in the
lazarus interface. Could you tell me how I should execute this gdb
command?

You could try to use this GDB command:
set scheduler-locking <mode>
Set the scheduler locking mode. If it is off, then there is no locking
and any thread may run at any time. If on, then only the current thread may
run when the inferior is resumed. The step mode optimizes for
single-stepping. It stops other threads from "seizing the prompt" by
preempting the current thread while you are stepping. Other threads will
only rarely (or never) get a chance to run when you step. They are more
likely to run when you `next' over a function call, and they are completely
free to run when you use commands like `continue', `until', or `finish'.
However, unless another thread hits a breakpoint during its timeslice, they
will never steal the GDB prompt away from the thread that you are debugging.
show scheduler-locking
Display the current scheduler locking mode.
